Vulcanized and non vulcanized PP/EPDM toughening master batch were prepared by two step blending,and then used to the modification of PP.Obvious difference was shown between the micromorphology and rheological behaviour of the modified blends.The vulcanizing agent used could result a dynamic vulcanization to the EPDM in the PP/EPDM blend,and make PP graft onto the crosslinked network of EPDM.The EPDMin non vulcanized system was shaped like fibrous...

Vulcanized and non vulcanized PP/EPDM toughening master batch were prepared by two step blending,and then used to the modification of PP.Obvious difference was shown between the micromorphology and rheological behaviour of the modified blends.The vulcanizing agent used could result a dynamic vulcanization to the EPDM in the PP/EPDM blend,and make PP graft onto the crosslinked network of EPDM.The EPDMin non vulcanized system was shaped like fibrous root and distributed among and inside the PP spherulites,and the EPDM in vulcanized system distributed mainly among the PP spherulites,being a "sea island" structure and having an obvious boundary transition with PP spherulites.When EPDM content was the same,the impact resistance of vulcanized system was higher than that of non vulcanized system,and this difference would be more obvious when EPDM content increased.Rheological analysis showed PP/EPDM blend was a pseudo plastic fluid( n <1),and on certain shearing rate the increase and vulcanization of EPDM would make the appearing viscosity η a increase,extrusion swelling ratio B and non Newtonian index n decrease,and non Newtonian fluid property become more obvious.

本文采用二段共混方法,先制得PP/EPDM硫化与非硫化增韧母料,该两种母料对PP的改性,其共混物的微观形态及宏观力学性能显示极大的差异。所采用的硫化剂可以使PP/EPDM共混物中的EPDM发生动态硫化作用,且使PP接枝于EPDM交联网络上。非硫化体系中EPDM呈根须状分布于PP球晶之间和内部;而硫化体系中,EPDM主要分布于球晶间,与PP相呈“海-岛”结构,并与PP球晶有很好的界面过渡。在EPDM含量相同的情况下,硫化体系比非硫化体系具有更高的耐冲击强度,且EPDM含量愈多时,这种效果愈加明显。流变行为分析表明,PP/EPDM共混物属于假塑性流体(n<1),在一定剪切速率下,EPDM含量的增加及EPDM的硫化,都使共混物的表观粘度ηa增加,挤出膨胀比B减小,非牛顿指数n减小,非牛顿流体性质更明显。

Nylon 6 showed low impact strength values. Whereas the addition of thermoplastic polyamide elastomers (TPAE)2533SA and E40S3, Nylon 6/2533SA and Nylon 6/E40S3 alloys showed high impact strength values. POM and SEM observations of the fracture surfaces and deformed regions beneath the fracture surfaces revealed that the fracture process of nylon 6 was brittle which was originated from plastic constraint at the notch tip. The fracture of alloys was also caused by plastic constratint at the notch tip. However,...

Nylon 6 showed low impact strength values. Whereas the addition of thermoplastic polyamide elastomers (TPAE)2533SA and E40S3, Nylon 6/2533SA and Nylon 6/E40S3 alloys showed high impact strength values. POM and SEM observations of the fracture surfaces and deformed regions beneath the fracture surfaces revealed that the fracture process of nylon 6 was brittle which was originated from plastic constraint at the notch tip. The fracture of alloys was also caused by plastic constratint at the notch tip. However, the plastic deformation zone at the notch tip was composed of many voids and partially elongated fibrils, and this absorbed impact energy. The plastic deformation was enhnaced by the transition of the stress state from plane strain to plane stress. The final fracture occurred from the notch tip connecting voids in the plastic deformation zone.

尼龙6与在尼龙6中分别添加了两种热塑性聚酰胺系弹性体的尼龙6合金相比,前者的耐冲击强度低,后者的耐冲击强度高;通过偏光显微镜和扫描电镜的观察,尼龙6在U型缺口前部区域内的塑性约束下,呈脆性破坏;尼龙6的合金因塑性区域内的空洞化和空洞的变形及空洞之间区域的颈缩和纤维化,有效的吸收了冲击能量,使塑性约束得到缓解,促进了平面应变状态向平面应力状态转变,最终呈半韧性或韧性破坏.
